being secured to Ll ircssion mmnhcr, x'vhereas the other end or the member shaped to provide a saddle u the roi'lnd rod tension member. In order ororide a support adapted for ue in conion with an auangement such as do i I l have provided a clevis which is l to be secured to the strut by means "vet which passes tirough a vertical -e located at the tension member end strut. This forms an extremely ece- ",il means of connection to the third support.

This fulcrum comp of metal, bent to provide two e ."ms 16, A. saddle 18 is formed in one end to ucconnno date the tension rod 19 of the brake beam. The other end of the sit-rut is connected by means of the ears 20 to' the channel compression member 21. After the shank 15 has been inserted in the aperture, it is Elli eteil over, as 52 In the construction shown Figs. 3 and l, the strut. remains the same, the clevis being slightly modified. In'this instance it comprise a her or strip of motel which is bent into llehane, providing a llet por tion 523, which liee against the strut and is apertured to accommodate the fastening rivet 24:; the cleric is then bent to provide two arched portions 26, which terminate in apertured ears 2?, 28, which serve to connect the third point supoort.

in the construction of Fig. 5, the struts likewise remains the same, the bracket or clcvis comprising a flat strip 29, apertured to accommodate the rivets at one end and doubled upon itself to provide the eye 31 at the other end, by means of Whic eye the third ooint supporting means are connected lly reason of the construction showing e sinipl a and an economical form of (JOBHBClJlUl'L is provided for a forgi-zd fulcrum and a third point supporting means, this being accomplished Without weakening the strut and without material increase in the cost of production.

I claim:

r 1. in a brake beam, the combination oil a tenHion member, compression member and strut, said strut being composed of? a single piece ol? metal forged to the required shape, and having a i'crtic; l aperture near one end thereof, third point supporting means, including a clevis and a rivet passing through said aperture and securing said clevis in place.

2. In a brake beam, the combination of a, tension member, compression member and strut, said strut being composed of a single piece of metal forged to the required shape, and having a verticz l. aperture near the tension member end thereof, an arched support ing membe' above the beam, a clevis pivot-- ally connected to said supporting member,

Ill

said clevis having an integral shank adapted to enter said aperture, substantially as described. v 3. In a brake beam, the combination of a '5 tension member, compression member and strut,- said strut being composed of a single piece or metal forged to the required shape, and having a vertical aperture near the tension memberend thereof, an overhanging 10 third point suspension including a clevis and vertically disposed fastening means c0- operating with said aperture and fastening said ClQYlS to said strut, substantially as described.
